| Summary |
With the recent development of intelligent transportation system, how to effectively and quickly display a large amount of traffic information to managers is a major issue. Visualization is the most common and important channel. However, there is still much room for improvement in real-time traffic visualization in Taiwan nowadays.
The purpose of this study is to improve two major problems of the existing real-time traffic visualization system. First, Users are prone to overlap between screen zooms, causing visual clutter. Second, there is the lack of information between space-time and attributes. The visualization in this study is designed for real-time traffic visualization to traffic control administrators in county and city areas of Taiwan. The contributions of this study are to propose a real-time road visualization that avoids the above two problems and is applicable to the county and city areas in Taiwan. The visualization has a hierarchical information organization, covers the two main road information of speed and incident, and uses a ring type visualization to reduce the learning cost.
In this study, the feasibility of visualization was verified by using the actual Link of information in Hsinchu County, and the visualization design was examined through visualization criteria. The overall results were presented in a highly restorative interactive prototype to show the actual interaction between the overall system and the manager, which can be used as a reference for the future enhancement of the existing real-time road visualization in Taiwan. |
